Basic Tablet Weaving

Introduction

Card weaving, also known as tablet weaving, is a method of producing narrow textiles such as

straps, belts and trim. Most card woven bands are very strong and sturdy. Card woven bands

can range from simple and easy to elaborately patterned and very time consuming. I'll focus

on the easiest types, but I will tell you where to find out more about the more complicated

types of card weaving.

The oldest known reliable evidence for card weaving comes from about 400 B.C. Several

cards and some card woven material was found at an archeological site in Spain. In period,

card weaving was most highly developed in northern Europe, especially in Scandinavia, and

was also used by the Anglo-Saxons. Many medieval pieces were ornate silk ecclesiastical

vestments, or wrist and head bands brocaded with gold or silver, but others were much

simpler. These may have been used as belts or straps. Card woven borders were sometimes

woven into larger textiles. This helped to set the warp spacing and provided sturdy selvages.

Materials

Cards can be made of thin sturdy cardboard, or even thin wood. The material must be smooth

enough that it won't catch the yarn. An easy set of weaving cards can be made from an old set

of playing cards. Index cards also work, but aren't very sturdy. What ever the material, the

cards should be cut into squares about 5-6 cm on a side, and a hole punched in each corner.

Make sure the holes are smooth and nearly round, or you will have trouble turning the cards.

It also helps to round the corners.

A wide range of yarns work well for card weaving. Whatever you choose must be fairly

sturdy. The warp (the yarn strung thru the cards) will be under a lot of tension and friction, so

it can't be anything fuzzy or easy to break, although fuzzy yarns can be used in the weft. I've

found that cotton crocheting string works well (and is cheap and easy to find) but embroidery

floss can also be used, or any sturdy yarn.

Setting Up

The first step (after making cards, finding yarn and picking a project) is to cut the warp. The

length of each warp string should be the intended length of the finished piece plus 20% for

take-up, plus 50 cm for room for the cards, starting and ending knots, etc. This is important,

so I'll repeat it:

warp length = 1.2 x final length + 50 cm

One warp yarn will be strung through each hole in every card. A card can be strung from left

to right (Z-threaded) or right to left (S-threaded), but all four holes must be strung in the same

direction or the card won't turn. When you look at the cards from above, the yarn will be on a

slight diagonal, either in the same direction as the middle line of a Z, or the same direction as

the middle part of an S. It's probably easiest to tie each set of four warp yarns together after

you thread a card. When all the cards are threaded, tie a big knot at the beginning and the end

to hold everything together.

The weft is the yarn that is passed back and forth between the warp threads, and holds the

whole thing together. It will normally only show at the sides of the band. Take a fairly long

piece of string (but not too long or it gets unmanageable) of the same color as the strings in

the edge cards, and wind it around a shuttle or make in into a butterfly. Now you are ready to

weave!

Weaving

Tie the far end of the warp to something sturdy, like a doorknob or a chair. Either hold the

other end or attach it to your belt. The cards should all be in a pack with one set of edges flat

towards you. Pass one end of the weft through the shed, which is the gap between the warp

threads in the top holes of the cards and those in the bottom holes. Leave about 2 cm or so

sticking out of the weft. Turn the entire pack of cards one-quarter turn, either forward (away

from you) or backwards (towards yourself). The direction depends on the pattern. Pack the

new shed towards yourself, wither with your finger or something smooth and flat, like the

back of a knife blade, and pass the weft through again. Don't pull the weft all the way tight

yet- leave a little loop sticking out. Now repeat the following steps:

1. Turn the cards.

2. Pack the shed.

3. Tighten the previous weft shot just to the edge of the band.

4. Pass a new weft shot through the shed.

Continue until the band is the length you'd like. Easy, isn't it?

Finishing

Trim can be cut into lengths and sewn on, as long as the ends are firmly sewn down. For

straps or belts, you can leave extra and make tassels or braids, or hem the ends. Or for a belt,

you may want to attach a ring to one end. Just don't forget to take the cards off!

Threaded-in Patterns

Now that you know the mechanics of card weaving, you probably want to know how to make

neat patterns, right? The easiest type of pattern is the threaded-in pattern, where the design is

created by threading different colors of yard in the same card, and all the cards are turned in

the same direction. These patterns are not medieval! Most period patterns involve some

amount of individual manipulation of the cards. Any of the references at the end can give you

more suggestions about medieval card weaving.

Card weaving projects are usually set up from a pattern. The conventions I use are similar to

those used by Collingwood and other authors in this area. Each hole in the card is given a

letter to identify it. You don't need to write these on the card unless you really want to, but it

is useful to mark to top of each card in some way. Most commercial cards are marked.

Looking at the card from the left, the letters are:

D A

C B

A pattern will show the order of the cards, what color weft to string through each hole, and

the threading direction, and can be drawn quickly on graph paper, with each column of four

squares indicating the four holes of one card. A \ below a column indicates that card is S-

threaded, and a / indicates a Z-threaded card. The following sample pattern would be for four

cards with dark threads in their B holes and light threads in the remaining holes. The left two

cards are S-threaded, and the right cards are Z-threaded.

O O O O D

O O O O C

X X X X B

O O O O A

\ \ / /

I have made a page with a few sample threaded-in patterns, and descriptions of the bands they

will produce. Notice that for a Z-diagonal stripe to have smooth edges on the front of the

band, the cards must be S-threaded and turned forwards. If S-threaded cards are turned

backwards, a smooth S-diagonal stripe will result. The opposite is true for Z-threaded cards: if

turned forwards, they will produce a clean S-diagonal. This effect is caused by the twisting

together of the four threads in each card. Patterns with no diagonal lines usually work best

with alternating Z and S-threaded cards.

More Complicated Patterns

One of the most common individual card manipulations is the twist. Simply rotate a card

around its vertical axis. This changes the threading direction of the card as well as the color

position. (Note: In some cases twisting the card is equivalent to turning it in the opposite

direction. A Z-threaded card turned forwards will produce the same twist as an S-threaded

card turned backwards, but the color pattern may not be the same with a twist as a reversal.)

One pattern I really like is kivrim , which makes a spiral design.

Double Face Weave

This is the simplest weave that allows you to make patterns that do not depend on the

threading of the cards. Nearly any two-colored pattern can be made using this weave-

pictures, letters, even Celtic knotwork.

Set up all the cards with two dark threads in the holes nearest you (A and B) and light threads

in the far two holes (C and D). The cards should alternate S and Z-threading. The basic double

weave sequence is: 2xF, 2xB. This turning sequence will make a band that is all dark on the

top and all light on the bottom.

To switch colors in one card, simply twist that card when it has two different colors in the top

two holes (the dark threads are in A and D, or in B and C). The card or cards twisted will now

make a portion of the band with a light surface and a dark back. Having control over the color

of each individual card allows you to weave any pattern that you can draw on graph paper, as

long as each color change is a multiple of two squares long. This restriction is because you

can only change colors in the first and third card positions in the sequence, and not in the

second and fourth (twisting will have no effect on color position.)
